BRAKE.

Application filed January 20, 1905.

T ztZl whom it may concern:

Be it known that I, JAMEs W. TAPP, a citizen of the United States,residing at Wichita, in the county of Sedgwick and State of Kansas, haveinvented certain new and useful Improvements in Brakes, of which thefollowing is a specification.

This invention embodies a novel form of brake mechanism particularlydesigned for wagons, portable machines, or vehicles of any type.

The invention embodies improvements in friction-brakes of the typeemploying a rotating brake-wheel and cooperating brakeband, theconstruction of the friction devices being such as to give a maximumamount of braking action for the purpose of the invention.

Further, the invention includes a peculiar combination of friction brakemeans and the ordinary construction of brake mechanism utilizing abrake-beam and brake-shoes directly engaging the wheels.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features of the invention, still the preferredembodiment thereof is shown. in the accompanying drawings, in which-Figure 1 is a perspective view showing the rear portion of a vehicle,the invention being applied thereto. Fig. 2 is a perspective view of thebrake-band and adjacent attaching devices. Fig. 3 is a detailperspective view of the brake-wheel. Fig. 4 is a vertical sectional viewthrough a brake-wheel having the brake-band applied thereto, bringingout more clearly the form of the sections of the brake-band.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

In illustrating the application of the invention as when in actual usethe rear portion of a wagon or similar vehicle is shown, the rear axlebeing indicated at 1, the adjacent hounds at 2, the wheel 3, and thehubs 4.

Patented April 17, 1906.

' The vehicle structure may be of any suitable type, as above premised.

The brake mechanism comprising the invention consists, primarily, ofbrake-wheels 5, which are attached to the hubs 4 of the wheels 3. -Thebrake-wheels 5 are of circular formation, so as to receive the body ofthe hubs 4, and these wheels 5 are attached to the main or ground wheelsof the vehicle by means of bolts or similar fastenings, which passthrough openings 6 in the wheels 5 and engage with the spokes toaccomplish the desired function of attachment with the brake members 5aforesaid. It is contemplated that the brake-wheels 5, however, besecured for rotation with the ground-wheels 3 in any suitable manner,and the peripheral portion of each of these wheels 5 is preferablygrooved.

Cooperating with each of the wheels 5 is a brake-band of peculiarformation, said band being of sectional construction. The sections ofthe band aforesaid are designated 7 and 7 and these sections are pivotedto gether at one 611d, as shown at 8. The 0pposite end of the sections 7and 7 of the brake-bands are connected together in such a manner thatthe sections may be caused to frictionally bind against the brake-wheel5 or loosely engage the same in their ordinary braking operation. Ashort lever 9 is pivoted at one end to the lower section 7 of eachbrake-band, and this lever 9 is connected at a point between its endswith the upper section 7' by means of a link 10. The end of the lever 9opposite that pivotally connected with the lower section of operablyconnected with an actuating rod or bar 11, to which power iscommunicated in effecting the braking action of the brakebands. Themeans for actuating the brakebands may be of any suitable type, and forthis purpose a shaft 12 is mounted upon the pulled or pushed rearwardlythe lever 9 will the brake-band is truck of the vehicle, upon the houndsin the be actuated thereby, so as to effect a closing movement of thesections of the band with relation to each other, so that such sectionswill bind against the brake-Wheel and admit of application of the brakesin this manner. When the levers 9 are not actuated in the above manner,the same admit of free move ment of the brake-wheels in the brake-bandsin a manner readily apparent. It will be understood that when thevehicle is being backed the shaft 12 is operated to force the lever 9 inone direction, whereas when the vehicle is moving forward the said shaftis actuated to throw the lever 9 in the opposite direction in operatingthe brake mechanism. The provision of the lever 9 gives an increasedamount of leverage at a very advantageous point with reference to thesections of the brake-bands, and the increased leverage thus obtainedgives a great amount of power. The uppermost sections 7 of thebrake-bands are grooved upon the under sides thereof and are wider thanthe brakewheels 5, with which they engage, in order to house the upperportions of the brake-wheels, and thereby prevent dust or like foreignmat ter from interfering with the proper frictional contact of thebrake-bands with the said wheels 5.

The brake-bands are operably connected with a brak-beam 14, which ishung from the hounds 2 of the vehicle, preferably, said beam 14 beingprovided with the usual brakeshoes 15. The connections between thebrake-beam 14 and the brake-bands are peculiar and consist of chains orsimilar devices 16, one of which connects the brake-beam 14 with onesection of a brake-band, another of said chains or connectionsconnecting the brake-beam with another of the sections of thebrake-bands, so that the brake maybe applied when the vehicle movesforward or is backed. The brake-beam 14 is connected with thebrake-bands near its ends and the movement of the sections of thebrake-bands in throwing the levers 9 forwardly is com municated to thebrake-beam by means of the connections 16, above described. Thus whenthe vehicle is advancing and the levers 9 are forced forwardly thechains 16, connected with the lower sections of the brakebands, arepulled rearwardly by binding of the bands, throwing the brake shoes 15against the wheels 3 in the usual manner, and the operation is thereverse when the levers 9 are pulled upon and the vehicle is beingbacked.

The general operation of the brake mechanism is clear from the fore oingdescription, and an essential feature of the invention is comprised inthe structure of the arious parts, whereby the same may be readilyapplied to almost any type of vehicle now in use, various parts of theinvention being at the same time comparatively simple and economicallyconstructed from the standpoint of cost and manufacture.

Having thus described the invention, what is claimed as new is 1. In abrake, the combination of a brakewheel, a brake-band cooperatingtherewith and composed of sections pivoted together at one end, a leverpivoted to the opposite end of one of the sections, a link connectionbetween the lever and the other section, and means for operating thelever as specified.

2. In a brake, the combination of a brakewheel, a brake-band composed ofsections pivotally connected at one end and embracing the brake-wheel, alever pivoted at one end to the opposite end of a section of thebrake-band, a link pivoted at one end to the opposite end of the othersection of the brakeband, said link being pivoted at its opposite end tothe lever between the ends of the latter, and means connected with theend of the lever opposite that attached to the brakeband for actuatinsaid lever.

3. In a brake, the combination of a brakewheel, a brake-band thereforcomposed of sections, one of said sections being wider than thebrake-wheel so as to house the same, and means for actuating thesections of the brake-band as specified.

In testimony whereof I affiX my signature in presence of two witnesses.
